UNITED STATES PATENT OFF ICE BERNARD I. IULDOON, OI IOUNTAIN VIEW, NEW JERSEY, ASSIGN'OB TO HENRY man, or naoox'mm, new YORK rmsn. near 7 Application filed Kay 7,

This invention relates to a flash li ht of which the casin is made up of insu ating material, such as akelite for example,-that 1S appreciably strengthened bymeans of Ion i- K I casing and the main or body portion of the 55 tudinal ribs along the insIde thereof. T e casing is closed at one end, except for a small hole to facilitate removal of'the battery and is enlarged at the other end to provide space fora reflector, etc. A conductive strip is of the casing, havin a resilient bent portion at one end to press t e battery into contact with the electric bulb and having the other end disposed to be pressed against the reflector to complete the electric circuit.

The invention will be understood from the description in connection with the, 'accompanyiug drawing'in which Fig.1 is a vertical section'through an illustrative embodiment of .the invention; and Fig. 2 is a section taken along the line 2-2 of Fig. 1.

In the drawing reference character 1 indicates a casingof insulating material, such as bakelite for example, that has an enlar ed end 2 for the reception of arcflector and ot er parts of the device. Lon itudinal internal ribs 3 may be provided a on 'the insideof I the casin 1 to strengthen t e same. The lower emf! of the casing is entirely closed,

except for an opening 5 through which a in or the like may be inserted to push the atter out of the casing when it is desired to rep ace the same with a new one. i The enlarged end 2 of the casing is inter- 3-- nally threaded, as indicated at 6 and'an externally threaded sleeve 7. is ada ted to be screwed into the enlarged end. '-T e sleeve 7 is provided with a flan 8 and shoulder for the reception of the rim of, a lens 9 that may 4 be kept in place in the flange by means of the wire 10 in a well known manner. A reflector 11 has its rim also xtendin into the flan d portion of the sleeve. 7 below the lens 9. T he reflector 11 is provided with a screw threaded sleeve portion 12 into which an electric light bulb 13 may be screwed. The center contact 14 of the bulb 13 contacts with a terminal of the battery 15 that may be made up of two cells in the .usual way.

The battery is spring pressedagainst the m. Serial mi. across.

center contact 14 of the bulb 13 by means of the bent or folded back end 16 of a resilient 'metallic strip 17 The bent or folded back end 16 extends acrossthe lower end 4 ofv the The current passes from the battery 15 through the contact 14, filament of the bulb 13, sleeve 12, reflector. 11,, strip 17 and bent end 16 back to: the battery, when the switch 19 is in position to cause the end 20 to contact with the reflector 11.
